Engine Performance problem
2001 Chevy Suburban V8 Two Wheel Drive Automatic 129000 miles
I just purchased an '01 Suburban and notice now that the oil pressure drops (to about 7-8psi) and the check engine oil light comes on when the car is at idle/ decelerating. I've had the pressure mechanicaly checked which confirmed the low oil pressure, the sensor was also replaced because it was a very cheap model. But still having the same issue.
Is it possible to diagnose the problem given this information.I've been told that it could be
1. Oil screen inside the oil pan
2. Oil Pump
3. Excessive Engine wear
have the same problem?
